Answer:
Step-by-step explanation:
In this exercise, we have two equations, namely:
And we are asked to solve this problem by graphing. In this way, we can write a system of linear equations in two variables, but first of all, let's rewrite:
Then:
So here we have two lines.
The first one is:
This line passes through the origin and has a slope 
The second one is:
This line has a slope 
and cuts the y-axis at 
By using graph tools, we get the graph shown below, then:
Equal is the with the 38+
Said that the following year he was following his first start in the first orange in and mark on the following season in the first round
First subtract the number that did, to find the number that didn't.
1300 - 520 = 780 customers did not order coffee.
Now divide the number who didn't order coffee by total number of customers:
780 / 1300 = 0.6
Multiply by 100 to get the percent:
0.6 x 100 = 60% did not order coffee.
Hi there!
The answer is C.
The question has already revealed the following data:
x = number of tickets.
y = number of t-shirts.
We can now find the total cost function.
The cost of 1 ticket is $ 25
and therefore the total cost for all of the tickets is $25 ×
the amount of tickets, mathematically $25 × x, hence 25x.
The cost of 1 shirt is $ 12
and therefore the total cost for all of the tickets is $12 ×
the amount of shirts, mathematically $12 × y, hence 12y.
When making the total cost function, don't forget to include the service fee of $4.
Now we can conclude that the total cost function is the following:
Maya only has $130 and therefore the total cost must be smaller than or equal to this amount of money. The answer is C.
